There was a problem filtering reviews right now. Please try again later.
When the Edimax EW-7811Un arrived, I was able to use the default Windows-10 and Mini CD-ROM to install the driver and support software; however, neither solution worked for longer than several minutes before failing. Most troubling was that the Edimax EW-7811Un “ALMOST” worked.
When I read the current product reviews, as they pertain to Windows-10, I realized that my experience was not unique and there were a number of unhappy people who ordered the Edimax EW-7811Un for use with Windows-10. In reviewing several USB WiFi solutions on Amazon, I noticed that the Windows-10 upgrades were more problematic. This could be caused by (1) older and slower hardware or (2) the Windows-10 upgrade image was not quite the same as a native Windows-10 image.
For several days I considered writing a scathing review while devising alternative solutions but kept returning to the fact that the software was almost on the cusp of working. Finally, I called the Edimax support number, expecting technical support Hades, only to be quickly connected with a knowledge support technician. When I described the problem, the technician indicated that the wrong software was being distributed for Windows-10 and provided guidance on where to find the correct software, which was not on the primary Edimax website. As Amazon doesn’t support the posting of URL’s, the following navigation is provided on where to find the correct software:
Navagation: edimax.us | support | download drives
On the “Driver & Manual Download” page, go to Section 7 and download the ZIP compressed driver EW-7811Un Win v220.127.116.11, which is the first entry in Section 7.
I used a tablet to download the file EW-7811Un_Windows_driver_v18.104.22.168.zip and then transferred the file to Windows-10 using a USB interface. Un-ZIP the file, using Windows-10, and then run the program “Setup”. This not a GUI and runs under a DOS shell, so just wait until it completes. As Edimax Support recommended, reboot your Windows-10 system, and you should be good to go!
A few off-the-cuff observations:
(1) A built-in laptop WiFi generally has a hidden and sometimes large antenna under the case. The Edimax may not work in WiFi marginal areas of your home. There are Edimax products with large external antennas but these will not have the small form factor of the Edimax EW-7811Un. If the connection is very poor the Edumax is flagged as “Turned Off” and you may have to use Windows-10 to re-enable the WiFi. This could be a bug!
(2) I noticed that the Edimax EW-7811Un sometimes appears to go to sleep. Turning Device “Power Management” OFF may correct that problem.
I have now run a four hour series of serious stress tests and, with the exception of marginal areas in my home, the Edimax EW-7811Un has performed well. I am giving this product “Five Starts” because of the good performance at a very affordable price point. Yes, Edimax’s software quality control was troubling in this case, but I would give their Technical Support “Six Stars” without a second thought.
Microsoft Windows-10 upgrade policy was highly innovative and has given new life to older hardware and after market upgrades such as the Edimax EW-7811Un. Edimax and Amazon have to do a better job of communicating the good news to their customers.
Additional info for Debian and all ran as root (or sudo):
Once the OS is installed, you will need to run the following command:
ln -s /dev/null /etc/systemd/network/99-default.link
This will disable the auto rename of the interface that invariably "confuses" Debian and renders the nic useless. Once this is symlinked, simply reboot and bingo.
Alternatively, you can edit /etc/default/grub
Look for the line: GRUB_CMDLINE_LINUX="" and change it to: GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
Then run: update-grub then reboot
This does the same as the symlink and probably a lot cleaner
After running this for a few days. I am seeing much of what some of the others have been saying. I am seeing serious lags with this device. For example, accessing a share on my locale network will sometimes take 1 to 2 minutes before there is network activity and eventually produces a simple listing of a directory. The same goes for accessing the internet for that matter. Mind you, I have any and all sleep/hiber/power saving modes disabled. This does not happen when I remove this device and use my old Panda PAUO5. So there is something with this nic.
I can only speak for using this on Windows 10, so maybe the drivers are better on Linux/raspberry pi, but this thing has cost me hours of lost time and troubleshooting. At first the plug-n-play drivers detected it, but it wouldn't connect to any networks. I thought this might be some configuration issue with my router, but other devices worked fine. So then I downloaded official drivers from it, after which it would connect to a network, but periodically would drop connection.
I assumed that this was again, just my parents' bad older router, but now I've used it with two other routers and I just get consistently crazy and *different* behavior with each network. 50% packet loss, ping spikes of thousands of milliseconds, more dropped connections. I switched to this NETGEAR AC600 Dual Band Wi-Fi USB Mini Adapter (A6100) dongle and all the crazy just immediately went away.
EDIT: amazon filters out the youtube URL. Try searching for: "How to use Edimax EW‑7811UN WiFi dongle on Mac OSX 10.11 El Capitan." I hope others find this video help like I did.

Speeds were good and I could see no difference between wired and wireless using this adapter for normal browsing. Granted I didn't bother doing a load of speed tests as ultimately it serves one purpose for me and that's providing wireless for the old Rasperberry Pi 2 that I use for a long running home automation job hidden up in my roof space.
My house was built in the 1950s out of solid concrete and my walls are at least half a foot thick as are my ceilings and floors.... it could survive a nuclear blast but as a result it can sometimes be like living inside a Faraday cage (meaning wifi and phone signals can get blocked) but this little device has done a superb job at getting through two floors of solid concrete and through a handful of walls to go from the roof space down to behind the sofa were the router is hidden which is pretty impressive given it's tiny size.
Excellent adapter would happily buy again if need be.
Update - May 28th 2017: Far more reliable than dongle it replaced. Had a few drop outs, but happens far less frequently than before. Flashing blue light on dongle is very handy too.
I found the supplied mini cd which contains the drivers a bit useless so i downloaded the drivers from their website and got it onto the pc via a USB stick. I had a few driver installation issues until i copied the install files onto the pc from the usb stick before installing. After this it worked smoothly without issue.
Very easy and cheap way to get access to wireless internet via a device that can't currently can't do so. Highly recommended.
As an engineer, I find some people have a PC upstairs and (where there has been a problem with the internet) the router is downstairs. installing one of these will make your PC wireless.
the dongle itself is very small and only sticks out of the USB port by a few mm, which is handy if you need to put it in a laptop that will be moved around. Not too many years ago these were about 3-4 inches long and were a considerable pain.
Although it is possible to replace a wireless card in a laptop - this is a cheap and quick alternative that requires no real techy know how. Simply insert the CD that is supplied in the computer, install the software then plug the dongle into the USB port.
Update: I tried it again today when connecting my computer to my TV and it's so slow that it cannot even load Google. Rating reduced to 1 star.
It isn't fussy about which networks it connects to, unlike your laptop, which is probably why you're looking at this.
If you need long range WiFi, you will need something physically larger, such as a TP-Link T9UH - which is an impressive beast, but you're not going to leave it plugged in while porting your laptop about.
Most of the 1 star reviews are based on routers being unable to provide 2 channels (20/40mhz). Of course most end users don't know this and think its a misadvertisement. I have successfully been connected at 150mbps and the device happily stays connected at 90 - 120mbps most of the time. I am one floor above the router and can happily receive at least 90mbps from anywhere in the house.
I have now had this thing for about 6 years and recommend it as a cheap wireless device for work systems where a connection, albeit slow over range, is required. No users of this device at work have complained (there are 6) and I recently upgraded this thing to a Proster wireless AC device. That thing fell apart, I had 2 of them as the first one broke in a week! The second failed shortly after. So back to this super old but reliable little piece of marvelous cheap technology.
If you want something for the short term, I recommend this. Otherwise, avoid.
Great little adapter. Its the size of your fingernail but still offers rapid internet. I would like to add that it is much faster than my laptops stock wifi.
The only warning I give is as follow. DO NOT use the supplied CD for drivers!!
I spent 30 minutes trying to get it to work using the supplied CD drivers. I then did (what men do best) and ignored the manual and let windows find drivers online. Instantly the dongle started to flash and work.
Apart from this hiccup the dongle is great.
I have now started using this adapter in my new computer and oh dear. This adapter is like an old sports car. A pain in the backside to get going but a beauty when running.Its not uncommon to wake my computer up and spend 10 minutes trying to get the blasted thing to connect.
Quiet a shame seeing as it works really well once connected.....
I am sorry to say that I can not recommend this adapter.
Well after a few more days it is broken. It no longer connects to the internet.
What more do I have to say apart from I am very disappointed that it didnt last past a week.
By contrast, this Edimax is Plug & Play on Linux Ubuntu and Mint and has a decent range for such a diminutive device. Time will tell if it lasts the course but so far I am very pleased.
There are numerous people who have stated it does not work with Mac OS, I even asked the question myself and was told by a reviewer that it did not work. However IT DOES!!
Download the driver from http://www.edimax.us/html/english/frames/b-download.htm
And install before plugging in the dongle.
It does not work through Mac OS network settings, but rather through its own utility (why I only gave it three stars).
However it does provide wifi internet at reasonable speeds. I am yet to see blistering wifi performance speeds, or even similar speeds to the stock wifi card with my apple AirPort Extreme router, however it DOES WORK WITH YOSEMITE!!
Wether it will continue to do so with El Capitan who knows, for the moment I am just happy that it has allowed my aging Mac to remain useful
A good £6 worth of internet connectivity!
For installation in Windows, don't use the mini CD that comes in the box. Connect your laptop to the internet (using an Ethernet cable if you haven't got wifi) BEFORE plugging in the adaptor. After plugging the adaptor in, Windows will spot the new device and go off to find the drivers for you and install them automatically.
The Linux installation was more of a headache and it took me many, many hours of searching before I found a working solution. There is a baked-in driver in the latest Linux Kernel (3.11), but it doesn't seem to work for many people. Going to the Edimax website and downloading their driver package didn't work for me and going to the Realtek website was no better. The problem is that if you download the newest drivers from Realtek for the RTL8088CUS chip (which, confusingly, uses the RTL8192CU drivers), they either don't compile without error or cause a kernel panic.
The solution that worked for me (and many others, it seems) comes from Googling these terms: "github", "pvaret" and "rtl8192cu-fixes". I would quote the exact link, but Amazon deletes all links in reviews, regardless of how useful they are. When you find the page, towards the bottom of the page you will find some excellent instructions on how the install the drivers. You need to install git first ('sudo apt-get install git' in the terminal window), then just follow P Varet's excellent instructions. After a reboot I had stable wifi. My sincere and eternal thanks to P Varet for coming up with this solution and Timothy Phillips on whose work it is based.
Added 4 Jan 14 - Fitted this to my Raspberry Pi under Raspbian and it just worked!
After inserting and removing 4 times, the plastic part has broken. What remains is still able to carefully remove it from a USB slot and it does seem to still function (albeit badly, but then it was bad from the start). This won't be an issue for you if you intend for it to be for a single machine only.
If you are looking to provide wireless to a tired old desktop or laptop with no built in wireless running a lightweight linux distro to get some use out of your old tech, look elsewhere. I did not test this under a windows environment, where I suspect it's a lot less hassle.
